Very bad service from Discovery

I had a new car insured on my policy. It was a nightmare to first get a quote as I had the quote had to be sent to the risk department even though I am an existing client. I spent more than 4 hours on the phone with the call center to get a quote. Once I put the new car on my insurance policy and removed the old car Discovery automatically took R102 from my bank account without any explanation. Then on the 1st of August Discovery took an extra R1100 off my account through debit order for no apparent reason. They also had my insurance details incorrect saying the car was demo and not new. This would have had an impact on a claim should I have had one. I have spent an additional 2 hours on the phone trying to get my money back (the R102 and R1100). I have been waiting over a week for any explanation and for the supervisor to call me back. I have had no feedback what so ever. I have written numerous emails and no feedback. When I phone the call center they say they will phone me back they never do. I am so worried that the car is not insure properly after I have done everything according to the book. I will NOT recommend anyone to discovery. In fact I am getting quotes from other insurance companies to take my business elsewhere.With one of the many phone calls I had, the agent refused to give me a reference number. Above that when I eventually received a reference number (many calls later), when I phone again and give them the reference number I received there is no record of anything.
